The fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), is a devastating pest of maize, and host plant resistance offers a sustainable alternative to chemical control. This study evaluated the resistance of the maize germplasm CH1 against FAW through life table parameters, feeding and oviposition preferences and greenhouse experiment. Results showed that FAW larvae reared on CH1 exhibited significantly prolonged larval development (21.61 d vs. 12.49 d), reduced survival (65.00% vs. 94.00%), and lower fecundity (689.00 vs. 1369.93 eggs per female) compared to those on the susceptible control Huang C. Population parameters, including the intrinsic rate of increase (r) and net reproductive rate (R0), were significantly lower on CH1. Behavioral assays revealed strong feeding and oviposition preferences for Huang C over CH1. Greenhouse experiment confirmed that CH1 plants sustained only minor damage (Davis scale grade 2, resistant), whereas Huang C plants were severely damaged (grade 7, susceptible). These findings demonstrate that CH1 possesses multi-dimensional resistance against FAW, providing a promising genetic resource for breeding FAW-resistant maize varieties and supporting sustainable pest management strategies.
The inverse relationship between larval weight and development duration highlights the role of maize genotype in influencing FAW growth dynamics, with resistant varieties prolonging development and suppressing larval biomass accumulation.

Fall armyworm, Spodoptera frugiperda, is a major maize pest requiring effective and environmentally sustainable management strategies. This study evaluated the efficacy of Beauveria bassiana, Metarhizium anisopliae, pheromone traps, and their integration under field conditions in Iraq. Significant differences (P ≤ 0.05...
Background: Fall armyworm (Spodoptera frugiperda J. E. Smith) is an invasive insect pest of maize that can cause substantial foliar damage and adversely affect crop production. Host-plant resistance offers a sustainable and environmentally compatible approach for managing this pest; however, information on resistance i...

The fall armyworm, Spodoptera frugiperda (Smith, 1797), is a major agricultural pest worldwide because of its polyphagous feeding habits, broad geographic distribution, and high adaptive capacity. Although maize is its primary host, the species can attack more than 350 plant species across 76 botanical families, causin...

The efficacy of selected chemicals, botanicals and biopesticides against fall armyworm (FAW; Spodoptera frugiperda) on fodder maize var. African Tall was conducted from 2019 to 2021 at five locations in India. The pooled data revealed that at 3 days after spraying, the FAW population was lowest (16.53% infestation of p...
